• Recall Parallel and Perpendicular lines

• What are Polygons?

• What are Quadrilaterals?

• Squares and Rectangles in our everyday lives

  (Google classroom)

• Squares and Rectangles in our classroom

• Understand and state the properties of a Square

• Understand and state the properties of a Rectangle

  
  

• Polygons are 2d shape with a closed perimeter

• If there is a curve , it disqualifies it as a polygon

• A polygon is a shape that has many angles

• A polygon means a multi-sided shape

  E.g :

• Stars

• Arrow

• Octagon

• Square

• Rectangles

  
  

  Quadrilaterals

• Quadrilaterals are polygons with 4 sides, 4 angles and 4 vertices

• Quad means four

• Quadrilaterals come in different shapes

  E.g :

• Parallelogram

• Rhombus

• Trapezoid

• Kite

• Irregular

• Square

• Rectangle

  
  

-shapes that are closed

-shapes that are 2D

-shapes that have angles in it

-shapes that have vertices

quadrilaterals

-shapes that have 4 sides

-it is named because quad means 4

-examples: parallelogram, square, rectangle, kite, rhombus, trapezoid, irregular

• Polygons are two dimensional shapes.

• There are no open spaces.

• A shape that has a curved side is not a polygon.

• There are three parts a polygon is made of: sides, vertices, and angles.

  
  

  Quadrilaterals

• Quadrilaterals are polygons with four sides.

• Some types of quadrilaterals are parallelogram, rhombus, trapezoid, square, rectangle, irregular and kite.

• polygons are 2-dimensional shape and it is flat

• polygons is a closed shape

• polygons have 3 sides, vertices and angles

  
  

Quadrilaterals

• Quadrilaterals has 4 sides and 4 right angles

  • example of Quadrilaterals is:

    parallelogram, rhombus, trapezoid, square, rectangle and irregular

  
  

Polygons

1. They do not have any open sides

2. They are 2-D shapes

3. They have multiple sides, vertices and angles

Quadrilaterals

1. They have 4 sides, angles and vertices

2. Some quadrilateral shapes are parallel and some are perpendicular

   
   

   
   

• they are closed shapes

• they have sides, vertices and angles

• they are flat (2 dimensional)

  Quadrilaterals

• they have four sides

• there are 7 types of Quadrilaterals: e.g. rhombus, kite and trapezoid.

  
  
  

• it must be 2D

• polygons are flat

• they must be a closed shape

• cannot get inside to the outside

• it must be planar

• polygons are multi- sided

• they must have sides, vertices and angles

Quadrilaterals

• parallelogram

• rhombus

• trapezoid

• square

• rectangle

• irregular

• kite

  
  

Polygons

• is a closed shape

• is 2-dimensional

• have multiple sides

• must not have any curves

  Quadrilaterals

• have 4 sides

• have 4 angles

• have 4 vertices

  
  

Polygons:

• have straight sides, vertices and angles

• are closed shapes

• are flat (2 Dimensional), also known as planar

• at least have 3 sides

  Quadrilaterals:

• are polygons that have 4 sides, angles & vertices

• Some are squares, rectangles, rhombus & kite

• It must be 2D

• It must be Flat

• It cannot have an opening

Quadrilaterals

• Must have 4 angles

• squares

• rectangles

• kite

• have sides, verticals and angles

• closed shapes

• 2 dimensional and flat shape

• same surface

• planar shape

• make a 3 dimensional shape

Quadrilaterals

• a polygons with 4 sides, 4 angles and 4 verticals

• there are difference types

• is a closed shape

• 2 D (flat)shape

• all vertices

• Multi-sided

• cannot have a curved shape

• made of vertices, angles and sides

• cannot intercept

  Quadrilaterals

• has 7 different shape

• has 4 equal sides

• is a closed shape

• cannot have a curved line

1. is a close shape.

2. is a flat shape.

3. 3 parts=sides, vertices, angles.

quadrilaterals:

1. has 4 sides,4 angles, 4 vertices.

2. 7 different types of quadrilaterals.

3. the 7 different types of quadrilaterals is parallelogram, rhombus, trapezoid, square, rectangle, irregular, kite.

• Multi-sided shape

• Closed shape

• They are 2 Dimensional shapes

• They are flat shapes

• They have sides, vertices and angles

• They have straight sides

Quadrilaterals

• They are polygons that have four sides, four vertices and four angles

• There are seven different types of Quadrilaterals

• Polygons are shapes that has no gaps.

• Polygons are two dimensional shapes.

  
  

  Quadrilaterals

• They must be 4 sides

• They can be in different shapes

• The 3 parts of the Polygon is sides, vertices and angles.

• They are closed

• They are 2 Dimensional (2D)

  
  

  Quadrilaterals

• Quad means 4

• A Polygon with 4 sides, 4 angles and 4 vertices

  
  

• polygons only have straight sides ,vertices and angles

• polygons are 2 dimension

• all the sides of a polygons are closed

• polygons can make a 3 dimensional shape. Quadrilaterals

• have 4 sides,4 vertices and 4 angles

• Quad means 4

• there are a lot of types of Quadrilaterals

• They are always closed shapes like a cage

• They are 2D shapes/flat shapes

• They have many angles

• They are multi-sided

• The vertices must line on the same plane

• They can make 3D shapes

  e.g of Polygons:

• Triangles

• Quadrilaterals

• Pentagons

• Hexagons

• Octogons

• Squares

• Rectangles

3 Parts of Polygons:

-------------------------

• sides

• vertices

• angles

  ------------------------------

  Quadrilaterals:

• They have 4 sides

• They have 4 angles

• They have 4 vertices

  e.g of quadrilaterals:

• Parallelogram

• Rhombus

• Trapezoid

• Squares

• Rectangles

• Irregular

• kite

  ----------------------

• we see them in our daily lives

  
  

Only can be 2-D,have to be a closed shape.It also have to be a multi-sided shape. Made out of 3 parts:SIDES,VERTICES,ANGLES.Can use polygons to make a 3-d shape, no curved side

eg:square,rectangle,star,triangle

not a polygon: circle,heart

Quadilaterals

4 sides, angles

eg:

parallelogram,rhombus,trapeziod,square,rectangle,irregular,kite

Explain your answer

No ,because for a rectangle, only the opposite sides are equal. But for a square, all the sides are equal.

A rectangle is not a square.

Explanation:

All sides of the square are equal, but only the opposite sides of a rectangle are equal.

Is square a rectangle?

No. Square have equal sides while rectangle do not have equal sides.
